Introduction to the lighting power supply and control method of solar street light and other street lamps

The early design paid more attention to the pursuit of low cost. In the near future, a consensus has gradually formed, and high efficiency and high reliability are the most important. For example, the electric equipment capacity of high-pole light poles is 35.4kW, and the electric capacity of lighting is 66kW. The calculated load of electricity consumption in the road section is 263kW. According to the requirements of the design specification and the special box-transformer layout plan for the lighting of the street lamp pole project in the Longgang area of u200bu200bWuxiang New District, three box-type substations are set up to supply power to the street lamps, and the transformer capacity is 125kVA. (or be resolved by the owner and the relevant management department through consultation). A set of street light control terminal devices and intelligent power-saving cabinets are installed in the box-type substation. The street light control has remote control, time control and manual control for the street light management department to choose. The box-type substation should be set in the green belt outside the sidewalk and should not occupy the sidewalk. The street lamp power distribution adopts a three-phase four-wire system, each lamp is connected to a 220V power supply, and the loop voltage loss is about 5% to 7%. Metering: The total electric energy metering device is set up in the box-type substation. In addition, in order to measure the electricity load of different electricity prices, the advertising light box is equipped with a separate meter. 400W of advertising light box load is reserved on each street light pole; 5,000W of electricity is reserved for each bus shelter; 10kW of public service advertising light box is reserved for every 1,000 meters; 3,000W of electricity is reserved for traffic lights at each intersection; and other backup circuits.
